Pan Tilt Issues

We have some new MLs and I built the Lighthack box (no encoders on ELE2) and everything works really well. Something I don't understand though;

When I 'home' P&T they show -270 and -135 and the little yellow dot in the "XY Window" sits bottom left. If I adjust - lets say Pan; as I move away from -270 toward zero, I see the dot moving to the right BUT the lamp does not move! Once I go past 0 (center vertical line) the lamp starts to move and by +270 has rotated 1 and 3/4 times. Same for tilt; No movement until I move into positive territory when things proceed as expected. I was wondering if there is any setting in the EOS I can set so I spread P&T movement through the negative and positive range?

Is this a standard fixture patch or a custom one you have created, sounds like something is strange with the ranges defined in the patch. Can you screenshot the screen for the fixture in patch that shows the dmx value ranges and user range value and home values. And post here.

It wouldn't explain the first part, but the second part of your comment is very often due to having another console online sending sACN with the same priority, it would own the levels until they were superseded by the other consoles i.e. positive pan/tilt.

Aha, you got me there. I could not find a profile for them so I wrote my own (my first)! We use it in mode 12 and I've attached a combined screen shot of my (Edit) "Ridgeyard" and a clean version of the hard to read 'manual'. Note, the fixture 'jumps' the Pan and tilt Coarse and Fine DMX addresses; 7 and 9 for Pan and 8 and 10 for tilt. I appreciate your looking at this for me. If this is unreadable I can send you separate screen shots (cropped)

If you click on the range -270 270 can we see the screenshot of how the range is defined,

I can see straight away your home is 0, it should be 32768 for a 16-bit parameter with a user value of 0 for centre.

Yes that was why I was wanting the other screen shot as we don't actually know his user value home is zero although likely.

Let me know if this is not want you want. Tilt is exactly the same except its -135 +135. Remin me what that "snap" is on the Pan Speed.

Yes this confirms the reason for the issue.

You have the user home at 0 ie the mid position between the -270 and +270 but the DMX home set as 0 which is the minimum DMX value. As Dan said you need to set the DMX home to the halfway position to match ie 32768

PS Should have added - this makes sense now so I updated the "DMX Home" to 32768 for both P&T and will try the profile when I go in. And added to my desknotes for future ref. Thanks.
